Re: [Calc][Discuss]Interoperability with Excel for SUMIF, COUNTIF, COUNTBLANK, DCOUNT, DSUM, ... with empty cells and and = empty string criteria.
@Dennis, I agree that conforming to ODFF is first goal. I add comments and attachment in https://issues.apache.org/ooo/show_bug.cgi?id=65221 From my understanding of ODFF, I give ODFF expect result for some formula related with empty cell in the attachment(xls). If there is any mistake, please comments. Open this file in AOO3.4/LO3.5, 16 cases fail. There are: Criterion in COUNTIF/SUMIF ODFF AOO3.4/LO3.5 criterion as = empty cellempty string cell criterion as not empty cellnot empty cell and not empty string cell criterion as 0any cell exceptany cell except 0, not including empty cell value 0, including empty cell Criterion in criteria for database formula, such as DSUM, DCOUNT ODFFAOO3.4/LO3.5 criterion is emptyvalue 0all cells cell criterion is emptyempty stringall cells string criterion as = empty cellempty cell and empty string cell criterion as not empty cellnot empty cell and not empty string cell Also AOO3.4/LO3.5 has self-consistent problem. The different result for same criterion between COUNTIF/SUMIF and database formulu(DCOUNT/DSUM). These criterion includes: criterion is empty cell, criterion is empty string, criterion is =, criterion is 0 While, open this file in Excel 2003, 8 cases fail. There are: Criterion in COUNTIF/SUMIF ODFF Excel 2003 criterion is empty string cellempty string cell and empty cell criterion is emptyempty string cellempty string cell and empty cell string Criterion in criteria for database formula, such as DSUM, DCOUNT ODFFAOO3.4/LO3.5 criterion is emptyvalue 0all cells cell Also Excel 2003 has self-consistent problem. The different result for same criterion between COUNTIF/SUMIF and database formulu(DCOUNT/DSUM). These criterion includes: criterion is empty cell, criterion is empty string It seems Excel has better conformance for these test cases. Conform to ODFF is very important. Compatible with Excel is also very important, especially for some common used Excel scenario, such as COUNTIF(refrange, ) to count all cells displayed as empty. Do we have any chance to modify ODFF to solve this Excel user problem? On Tue, Jul 3, 2012 at 1:14 AM, Dennis E.

These scenarios are all related with pure empty cell. Excel use following rules When empty cell is criteria, only cells with value 0 meet it. This is true for COUNTIF, SUMIF. But not true for DSUM/DCOUNT/IF. When an empty cell in a cell range, it can meet empty string criteria. This is true for COUNTIF, SUMIF. But not true for DSUM/DCOUNT. first, I am not familar with spreadsheet formulas. I agree that interoperability with Microsoft Excel is important. But also important and from my point of view even more important is the conformance to ODF 1.2. I do not know, if the needed changes would cause an unconformance with ODF 1.2. If yes, things will be complicated. just my thoughts from an ODF perspective. Best regards, Oliver.

I believe that you should expand your area of concern. For example, I recently found a spreadsheet created and used in another spreadsheet program, don't know off hand if it was a Microsoft variant or a WordPerfect variant. The document was opened into Calc using OOo for a few years. When the document was tried on LibreOffice, it failed. Why? Because a few of the empty cells contained a single space and LO threw an error rather than dealing with it the way that the other programs had dealt with it. In this case, the only thing that I can say authoritatively is that LO and AOO treated the file differently. I did not pursue why LO made the change. My only point is that if you desire to argue that the functions in AOO should be changed to match those in Excel, you should also verify the behaviour of general numerical methods and how they treat cells with a blank. Off hand, I think that documenting the differences would be very valuable even if changes are not made to AOO. Perhaps even more important than compatibility with Excel is that the software that supports ODF natively are consistent. I am surprised that the ODF standard does not dictate how this should be handled. I was under the impression that function behaviour in an ODF document was well defined. I believe that Robert Weir is far more aware of ODF type issues than I (since I have seen him mentioned by name on similar topics) - not that I intend to unfairly pull him into this discussion. In Version 1.2 of the part-2 for OpenFormula, I don't see it obviously spelled out, but I don't really have time to extensively pursue it. The closest I see of say SUMIF is this: The values returned may vary depending upon the HOST-USE-REGULAR-EXPRESSIONS or HOST-USE-WILDCARDS or HOST-SEARCH-CRITERIA-MUST-APPLY-TO-WHOLE-CELL properties. 3.4 I did check the host defined behaviors section and that is primarily related to things such as locale and case sensitivity. Well, it does say this: 4.7 Empty Cell An empty cell is neither zero nor the empty string, and an empty cell can be distinguished from cells containing values (including zero and the empty string). An empty cell is not the same as an Error, in particular, it is distinguishable from the Error #N/A (not available).
